A large mass in the retroperitonium on the superior and lateral aspects of right kidney. The kidney was displaced inferiorly. Superiorly, the mass abuts the posterior aspect of the liver and narrows the inferior vena cava.
The tumor was well-circumscribed and there is no invasion of surrounding structures. The mass showed predominantly fatty regions interspersed with areas of higher attenuation inside. Density on CT varied between –60 Hounsfield units (HU) peripherally to –40 HU in the center. The mass is measuring 12.1 cm in its maximal diameter.
Two right hepatic lobe peripheral sub-capsular hepatic focal lesions are seen showing irregular enhancement on portal venous phase, and more homogeneous enhancement on the delayed phase, in keeping with haemangiomata.
